5962-8874001LA

Memory IC Overview

The 5962-8874001LA is a synchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a 16K-bit capacity organized as 2K x 8 bits with an access time of 35 ns. The device operates on a parallel interface and requires a core voltage supply of 5.0V. It is housed in a 24-pin Ceramic Dual In-Line Package (CDIP).

Memory IC Feature Summary

• Supports battery backup data retention capability for low-power standby modes.
• Utilizes fully static asynchronous circuitry requiring no clocks or refreshing.
• Features TTL-compatible inputs and outputs for standard logic interfacing.

Memory IC Applications

• Industrial control systems requiring non-volatile data storage via battery backup.
• Embedded applications utilizing standard TTL logic interfaces.
• Systems needing fast asynchronous memory access without clock synchronization.

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors due to the military-grade 5962 prefix. Confirm package integrity as ceramic packages are sensitive to mechanical stress. Check for lead-free compliance status if RoHS3 adherence is required for the specific assembly process. Ensure proper handling procedures for static-sensitive devices during installation.

Memory IC Selection Notes

Select this part when a 5V synchronous SRAM with 35 ns access time is required in a 24-pin CDIP package. Consider it for designs needing battery-backed data retention without complex refresh cycles. Evaluate compatibility with existing TTL logic levels. Compare against asynchronous alternatives if power consumption in standby mode is a critical constraint.

Memory IC Part Context

This component belongs to the Renesas 5962 series, which includes radiation-hardened and high-reliability memory devices. The 5962 prefix indicates a military-grade qualification standard. It is part of a broader portfolio of CMOS static RAM solutions designed for demanding environments where reliability and data integrity are paramount.

Memory IC Replacement Considerations

Direct substitutes include other 5962-qualified 2Kx8 SRAMs from Renesas or qualified equivalents from manufacturers like Cypress or Micron. Verify pinout compatibility and electrical specifications such as access time and voltage levels before substitution.

Memory IC FAQ
